VEHICLE-WRENCH.

Q'LtECIFIGATION forming part of Letters Patent No. 710,847, dated October 7, 1902.

Apnlication filed June 25,1902.

To all whmn it may concern/.

Be it known that I, LOT DAVIS, a citizen of the United States, residing at Ironton, in the county of Laurence and State of Ohio, have invented certain new and useful Improvements in Vehicle-Vrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements and means for removing and replacing the nuts upon axles of carriages, wagons, or the like; and it consists in a device formed with a nutengaging portion and a hub-engaging portion, the hub-engaging portion being adapted to be clamped upon the periphery of the hub of a Wheel, so that by turning the wheel the nut will be forced to move with-the same and may be screwed or unscrewed, as desired.

It also consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a perspective view of a wrench mechanism constructed in accordance with the present invention. Fig. 2is averticalcentral sectional view through the wrench as applied to the hub of a wheel and engaging the nut which holds the same upon an axle. Fig. 3 is a detail view showing a different way of constructing the clamping portion of the wrench mechanism.

The present invention is designed to supply a mechanism which may be employed for readily removing the nuts of vehicles from their axles, the said device being capable of such engagement with the hubs of the vehicle-wheels that when the wheel is turned the nut will be forced to move with the same for turning the nut off or upon the threads of the axle-spindle.

I am aware that devices of a similar character have been employed; but the present invention affords a very efficient means of securing the wrench mechanism to the hub of a wheel, and while the device is exceed- Serial No. 113,166. (No model.)

ingly simple in structureit is extremely effective for operating upon the nut of a vehicle-axle without marring or in any way disfiguring the hub of a wheel or the finished surfaces of the same.

The device forming the subject of this invention is made up of a nut-engaging portion 1 and a hub-clamping portion 2. The nut-engaging, portion is preferably a closed sleeve, as 3, which is made of suitable size to fit upon the nut to be turned. Upon opposite sides of the said sleeve 3 are hinged swinging arms 4:, which are capable of being folded along the sides of said sleeve upon opposite sides of the nut. One of the pivoted arms 4is secured to the clamp 2. The clamp 2 may be made in the form of a circle or a flat ring, as found mostdesirable, and is made of sufficient size to receive the end of the wheel-hub to be operated upon. The hinged arm 4, which is disconnected from the clamp 2, is arranged so that its free end may be brought within the ring of the said clamp, and a screw or bolt, as 5, is mounted in a screw-threaded aperture 6, formed in the clamping-ring at a point opposite the attached end of the opposite pivoted arm 4. When the free arm 4 is folded within the clam ping-ring, its free end is brought opposite the e'nd of the clamp-screw 5, so that by turning the said screw the said free arm 4 can be forced against the hub of the wheel. Of course at the same time the opposite side of the ring 2 and the pivoted arm which is secured to the same are drawn against the said hub. In this manner the Wrench mechanism can be firmly clamped to the hub of the wheel while the nut-engaging sleeve 1 is in proper position to inclose the nut which holds the wheel upon the axle. WVith the parts in this position the nut can be readily turned upon the threads of the axle-spindle by turning the wheel itself upon the axle. The free end of the free arm 4 is preferably formed with a recess or depression 7 to receive the end of the clamping-screw. This prevents the chance of the screw slipping upon the said arm when the device is being clamped upon the hub of a wheel.

iVhile I have shown in Figs. 1 and 2 of the drawings the clamping mechanism as formed of a continuous ring, yet it will be evident that I might form a clamp of a half-ring or G-shaped iron, as shown at 8 in Fig. 3. In this instance the clamp would be attached to the pivoted arm 4 in the same manner as the ring above described, and the clamp-screw at the other end of the half-ring will be in position to engage the other arm 4 in the same manner as above set forth. IVhen forming the clamp in this manner, I prefer to hinge the same to one of the arms 4, as shown at 9 in Fig. 3. With the clamp formed in this manner the semicircular iron S'may be turned back upon its hinge out of the way while the nut-engaging sleeve is being put into position. The semicircular clamp is then placed around the end of the hub and the clampscrew tightened, as above stated.

Among other advantages possessed by the mechanism just described may be mentioned the fact that the parts can be so clamped upon the hub of a wheel as to avoid any slipping with respect to the same, and yet not run any risk of scratching or marring in any way the finished surfaces of the wheelhub. I find in practice also that a clamp which surrounds an article can be made to engage the same with greater firmness, as a rule, than clamps which are placed within a cylindrical article.

It will be observed that the manner of hinging the arms 4: to the nut-sleeve facilitates the placing of the wrench mechanism in position or removing the same. I also contemplate lining the inner surfaces of the said pivoted arms 4 and any portion of the clampin g-ring which may engage the hub of a wheel with some soft or smooth material, so as to further avoid the scratching or marring of the finished surfaces of the huh.

I wish it to be understood that any minor changes which may be made I regard as within the scope of the invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- 1. A wrench mechanism for nuts of vehiclewheels, comprising a nut-engaging portion and a clamping-ring, a hinge rigidly secured to the clamping-ring at one end and carrying the nut-engaging portion at the other, a second hinge mounted on said nut-engaging portion having a free end, such free end adapted to be engaged bya screw seated in the clamping-ring, substantially as described.

2. A wrench mechanism for the nuts of vehicle wheels, comprising a nut inclosing sleeve, hinged arms'secured thereto, ahubinclosing ring carried by one of said arms and adapted to be folded over the other arm and around a hub of a wheel for securing the said wrench mechanism to such wheel so that it may be turned thereby, substantially as described.

3. A wrench mechanism for the nuts of vehicle-Wheels, coniprisinga sleeve forengaging a nut, arms hinged upon opposite sides of said sleeve and adapted to be folded back upon the same, a clamping-ring secured to one of said arms, and a clamp-screw carried by said ring and arranged to engage the other arm and force the same against the hub of the Wheel, substantially as described.

4L.- A wrench mechanism for the nuts of vehicle-wheels, comprising a clamping-ring, a nut-engaging member hinged to said clamping-ring, a hinged arm carried by the said nut-engaging member and adapted to be engaged by a set or thumb screw carried by the clamping-ring for binding the latter against the hub of the wheel, substantially as described.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.

LOT DAVIS.
